WATER-CLOSET OR URINAL.

SPECIFICATION forming part of Letters Patent No. 644,488, datedFebruary 27, 1900.

Application filed March 27, 1899.

To all whom it may concern:

Beit known that I, Mosns JAMES ADAMS, a subject of the Queen of Great Britain and Ireland, residing at Glenelg, Harrogate, in the county of York, England, have invented certain new and useful Improvements in Governed Multiple or Single Water- Closets or Urinals, of which the followingis a specification.

In water-closets and flushed urinals as heretofore commonly constructed the flush is caused by a discharge from a cistern controlled either by hand or by an automatic arrangement, the time of action of which is governed by the rate at which Water is supplied to the flushing-cistern.

The primary object of the present invention is to provide an automatic flushing device of such a nature that the flush only takes place when it is required by reason of sufficient use of the closet or urinal, whereby considerable savingis effected in the amount of water used.

Myimprovements are applicable to single as well as to multiple closets or latrines or urinals.

Other objects of my invention are to improve the construction of closets, more especially intended for use in schools, as hereinafter described with reference to the drawings accompanying this specification, in Which Figure 1 is a perspective view,partly in section, illustrating two connected closets and an automatic flushing apparatus constructed according to my invention; and Fig. 2 is a section of part of the apparatus, illustrating a modification.

A A are the closet-pans, each havinga flat back A, extended, as shown, to flt close against a wall, and so obviate the open spaces that usually exist between the closet-pans and the wall at the back thereof. The upper part of each back is raised at A and is made to connect to the flush-pipe B, which serves both pans. Hooks or hinges C O are secured in the front of the raised part A to engage with corresponding hooks in the seat D, which can be raised and lowered. The seats are horseshoe-shaped. The lower extremity of one of the pans unites, by means of asuitable socket connection, directly with the trap E, the other pan being connected to a lateral pipe F, which discharges into the trap E. In this way one Serial No. 710,663. (No model.)

trap is made to serve for a series of closets. Just below the upper bend of the trap is inserted an overflow-pipe G, communicating with a chamber G,whic'h is furnished with a siphon G for draining it. The said siphon discharges into the drain-pipe or outlet H. Within the chamber G, in the arrangement shown in Fig. 1, is a second chamber J, open at the bottom and closed at the top except for an air-pipe J, that passes up and enters the supply or flushing cistern K. Above the open end of the pipe J is an inverted bell or cap 0, suspended from the lever L of a supply-tap L. M is another supply-tap controlled by the float M in the usual manner, and N is a discharging-siphon of any ordinary'or suitable construction. The tap M is arranged to partly fill the cistern with water, so as to seal the mouth of the cap 0. The action is as follows: As the closets are used liquid overflows from the trap through the pipe G into the chamber G and, pressing on the air in the inner chamber J, drives it gradually through the pipe J into the cap 0, thus raising the latter and opening the tap L. The waterlevel thenrises in the flushing-cistern until siphonic action is started through the siphon N and a flush takes place. During the flush the chamber G fills sufficiently to start siphonic action in the siphon G which action continues until the chamber G is emptied, whereby the pressure is removed from the air in the pipe J, and the cap 0 then descends again and closes the tap L. The apparatus is now ready for another flush when the closet has been used sufflciently to reproduce the actions above described. The ball-tap M maintains a sufficiency of water in the flushihg-cistern to seal the lower rim of the cap 0.

In certain cases it may not be desirable to transmit air to the cap 0 for the purpose of starting the flush. In such cases I proceed as follows-that is to say, referring to Fig. 2, I dispense with the air-pipe J and the inner chamber J and transfer the supply-tap from the flushing-cistern to the chamber G. L is the water-supply pipe leading to the flushing-cistern through the chamber G, and L is a tap in said pipe controlled by a float L connected to the arm L of the tap.- When the liquid rises in the chamber G, it raises the float and gradually opens the tap L, and

so allows water to enter the flushing-cistern, whereupon the flush takes place, as above described. lVhen the discharge has been effected and the chamber G emptied again by the action of the siphon G the float L falls and shuts the tap L, thus stopping the further supply of Water to the flushing-cistern. \Vhen applied to urinals, the ordinary urinalbasin takes the place of the closet-pans A.

What I claim is 1. The combination with a water-closet or flushed urinal, of a chamber for collecting liquid from the outlet-pipe thereof, a second chamber within the said chamber, a siphon for automatically draining the first-mentioned chamber, a connection between said second chamber and the flushing-cistern, and means actuated by the rising of the liquid in the chamber for controlling the admission of wa-' ter to said cistern, substantially as specified.

2. The combination with a water-closet or flushed urinal of a chamber G for collecting liquid from the outlet-pipe thereof, a siphon for automatically draining the said chamber,

tween said chamber J and the flushing-cistern, the lever of the supply-tap and a cap 0 suspended from the lever of the supply-tap over the open end of the pipe J, substantially as described, and for the purpose specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MOSES JAMES ADAMS.
